    <p>I have written a partial view that displays a list of rows, where some fields in the row are editable using a textbox, checkbox, or whatever.</p> <p>I would like the parent view to have a "submit" button that posts the whole collection of updated rows so that I can do a group update rather than posting once for every updated row.</p> <p>Here's what I have:</p> <pre><code>public class GroupModel { public string SomeGenericProperty { get; set; } public IEnumerable&lt;ItemModel&gt; Items { get; set; } } public class ItemModel { public long ID { get; set; } public string Field1 { get; set; } public string Field2 { get; set; } } </code></pre> <p>Then I have a view "GroupDetails":</p> <pre><code>@model MyNamespace.GroupModel ... @using (Html.BeginForm("SaveItems", "Home")) { &lt;fieldset&gt; ... @Html.Partial("ItemList", Model.Items) ... &lt;input type="submit" value="Approve" /&gt; &lt;/fieldset&gt; } </code></pre> <p>And a partial view "ItemList":</p> <pre><code>@model IEnumerable&lt;MyNamespace.ItemModel&gt; &lt;table&gt; &lt;tr&gt; &lt;th&gt; &amp;nbsp; Field 1 &amp;nbsp; &lt;/th&gt; &lt;th&gt; &amp;nbsp; Field 2 &amp;nbsp; &lt;/th&gt; &lt;th&gt; &lt;/th&gt; &lt;/tr&gt; @foreach (var item in Model) { &lt;tr&gt; &lt;td&gt; &amp;nbsp; @Html.TextBoxFor(modelItem =&gt; item.Field1) &amp;nbsp; &lt;/td&gt; &lt;td&gt; &amp;nbsp; @Html.TextBoxFor(modelItem =&gt; item.Field2) &amp;nbsp; &lt;/td&gt; &lt;td&gt; @Html.HiddenFor(i =&gt; item.ID) &lt;/td&gt; &lt;/tr&gt; } &lt;/table&gt; </code></pre> <p>But when I post, the information from partial view is not being posted; the <code>GroupModel</code> object's <code>Items</code> property is null.</p> <p>What's the right way to do this?</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
